Soluble sugar content increased with decreasing water level and increasing density, whereas starch content decreased significantly with decreasing water level.
Last week, the governor of Lazio region, which includes the Italian capital, ordered that no more water be drawn from Lake Bracciano, which supplies some of the Italian capital, because the drastically decreasing water level posed danger to the aquatic life of the lake.
The decreasing water level and the adverse impact of industrial and agricultural activities, mining, urbanization, and global climate change are increasing the pressure on groundwater resources.
This study investigates the causes of decreasing water level in two wells (Ganga and Yamuna) inside the Jagannath Temple in Puri city, India, which is engendering water scarcity for day to day temple activities.
Hayes (2006a) also found that pesticide exposures have even more pronounced adverse effects when combined with other environmental stressors, including decreased water level, parasites, and increased population density.
The decreasing water level of the lake coincided with a decrease of mineralization (up to 80 - 35‰ in some larval habitats); in these periods, the respective habitats were moistened mostly with groundwater of lower salinity.
This might have been due to the decreased water level resulting from irrigation, thereby concentrating chemicals released from sediments, especially endosulfan, with a soil half-life of 120 days and sorption coefficient (Koc) of 17.52 L/g [ 23].
An article on Tuesday about decreased water levels in the Great Lakes misidentified the position held by Glen G. Nekvasil of the Lake Carriers Associationn, a trade group.
Clearly, the current uncontrolled digging up of numerous SDWs will not come without some costs, as past studies showed that areas most of SDWs developments are also hydrologically linked to the main aquifer supplying water in the city centre, the Makutupora basin which has already reported periods of decreased water levels (Rwebugisa 2008).
